20mm × 3.2mm Battery Equivalents

8 model(s) use the same nominal 20mm × 3.2mm outline. They span 3, 3.6V and LiMnO2, LiIon, LiCFx, so physical fit alone does not prove that one can safely replace another. Compare the printed code, voltage, chemistry, and device requirements before buying.

Which same-size batteries can replace each other?

The checks below compare each pair by size, voltage, and chemistry. “Closest match” still requires confirmation of drain rating and terminals; “conditional” means the device manual decides; a voltage mismatch means the pair must not be substituted.

CR2032 vs DL2032

Closest match

Size, nominal voltage, and chemistry match. Confirm drain rating, terminals, polarity, and the exact code before replacing.

CR2032 vs ECR2032

Closest match

Size, nominal voltage, and chemistry match. Confirm drain rating, terminals, polarity, and the exact code before replacing.

CR2032 vs CR2032L

Closest match

Size, nominal voltage, and chemistry match. Confirm drain rating, terminals, polarity, and the exact code before replacing.

CR2032 vs CR2032H

Closest match

Size, nominal voltage, and chemistry match. Confirm drain rating, terminals, polarity, and the exact code before replacing.

CR2032 vs LIR2032

Do not substitute

3V and 3.6V are different electrical classes. Matching dimensions do not make them interchangeable.

CR2032 vs BR2032

Conditional

The nominal voltage and size are close, but LiMnO2 and LiCFx have different discharge behavior. Follow the device specification.

CR2032 vs ML2032

Closest match

Size, nominal voltage, and chemistry match. Confirm drain rating, terminals, polarity, and the exact code before replacing.

DL2032 vs ECR2032

Closest match

Size, nominal voltage, and chemistry match. Confirm drain rating, terminals, polarity, and the exact code before replacing.

How to measure a battery with calipers

Battery dimensions are nominal and small manufacturing tolerances are normal. Dirt, a bent wrapper, raised terminals, or squeezing the jaws can shift a reading by a few tenths of a millimeter. Use the code on the old cell as the primary identifier and measurements as a check.

  1. Remove the battery and wipe the faces and edge clean. Do not measure it inside the holder.
  2. Close and zero the digital calipers, then measure the widest diameter without squeezing.
  3. Measure body thickness across the flat faces. Avoid raised button terminals or welded tabs.
  4. Repeat each measurement after rotating the cell. Treat about ±0.1–0.2 mm as normal measuring variation.
  5. Finally confirm the printed voltage and chemistry. Never select a replacement from dimensions alone.
